<p>In a high-pressure cleaner of the kind comprising a) a pump (1-3) for pumping cleaning liquid, the drive mechanism (12) of which is driven by b) an air-cooled motor (7), further c) an air cooler (8) adapted to be cooled by said cleaning liquid on its way to said pump (1-3), and d) air-circulating means (6) adapted to circulate air between said motor (7) and said air cooler (8) in an enclosure (4,23) containing the motor and the air cooler, the main novel feature is e) that that part (14) of said air cooler (8), through which said cleaning liquid flows, is in intimate thermal contact with or integral with a housing (11) containing the drive mechanism (12) of said pump (1-3). With this arrangement, the cooling capacity of the cleaning liquid flowing towards the pump (13) is also utilized for cooling the mechanism (12) moving the pump's pistons (2), in the example shown a swash-plate mechanism. <IMAGE></p> |
